if -2(3y+5) = -4 find the value of 5y

Question

Really struggling in class my teacher explains it strange and can't understand him

Answer 1

The expression simplifies to -6y -10 = -4 or 6y = -6 or y = -1

So multiply by 5 to get 5y = -5

Answer 2

-2(3y+5) = -4

-6y - 10 = -4

-6y = 10 - 4 = 6

y = -1

therefor 5Y = -5
